Which of the following is least likely to change the gene pool of a population of chipmunks?

a pesticide poisons and kills a large number of chipmunks.

a group of chipmunks moves to a new habitat.

a number of chipmunks die due to old age.

a genetic mutation causes some of the chipmunks to have larger eyes.

The number of death of Chipmunks due to old age is least likely of affect the gene pool of the population thus, option C is correct.

Further Explanation:

Gene pool refers to the group of all the genes or the genetic information found in any population, generally of particular species. The large gene pool reveals extensive genetic diversity that is linked with the robust populations which may survive bouts of intense selection. On the other hand, low genetic diversity may cause reduced biological fitness and an increased chance of extinction.

A larger gene pool indicates increased genetic diversity which increases the chances of biological fitness as well as survival. A small gene pool tells low genetic diversity and lower chances of acquiring biological fitness and a high possibility of extinction. Gene pool elevates when mutation takes place and survives. It decreases when the size of population reduces such as genetic disease.

When organisms died because of old age, they are most likely to be used up their productive capacity to transfer their genes as much as possible. This creates a condition where the gene pool of the next generation would be similar to the current one.
